Fund Objective

The T-REX 2x Inverse Nvidia Daily Target ETF (“NVDQ” or the “Fund”) seeks daily investment results, before fees and expenses, of -200% of the daily performance of Nvidia common stock ("NVDA").

Fund Performance

For the fiscal year ended June 30, 2026, NVDQ returned -56.12%, compared to a 26.82% return for NVDA and 22.32% for the S&P 500® Index.

Performance Drivers

As a fund designed to deliver -2x Nvidia's daily return, NVDQ faced a structurally adverse environment throughout the period. The stock's persistent upward trend — driven by continued AI infrastructure demand, a favorable competitive position in accelerated computing, and consistently strong financial results — acted as a sustained headwind.

Fund Objective

The T-REX 2x Inverse Tesla Daily Target ETF (“TSLZ” or the “Fund”) seeks daily investment results, before fees and expenses, of -200% of the daily performance of Tesla common stock (“TSLA”).

Fund Performance

For the fiscal year ended June 30, 2026, TSLZ returned -67.74%, compared to a 32.41% return for TSLA and 22.32% for the S&P 500® Index.

Performance Drivers

TSLZ seeks the inverse of Tesla's daily performance at 2x leverage, and as such was adversely positioned throughout a period in which the stock trended materially higher. Tesla's upward trajectory — supported by autonomous driving milestones, improving delivery volumes, and renewed investor enthusiasm for long-term growth prospects — created persistent directional pressure against the Fund. The daily reset structure compounded this effect: as Tesla appreciated day over day, each successive reset established a smaller NAV base against which subsequent losses were applied, mathematically accelerating the decline. Tesla's elevated intraday and daily volatility — one of the highest among large-capitalization equities — further amplified the volatility drag. The combination of a rising underlying trend and pronounced price volatility produced cumulative losses over the fiscal year that reflect both the Fund's inverse objective and the inherent compounding dynamics of a daily reset structure over extended holding periods.

Fund Objective

The T-REX 2x Long Nvidia Daily Target ETF (“NVDX” or the “Fund”) seeks daily investment results, before fees and expenses, of 200% of the daily performance of Nvidia common stock (“NVDA”).

Fund Performance

For the fiscal year ended June 30, 2026, NVDX returned 20.48%, compared to a 26.82% return for NVDA and 22.32% for the S&P 500® Index.

Performance Drivers

Despite Nvidia's strong full-year advance — underpinned by relentless demand for AI accelerators, favorable earnings results, and continued hyperscale investment — NVDX's cumulative return was substantially below twice the stock's annual gain. This outcome reflects the mathematical properties of the Fund's daily reset structure. When the underlying stock experiences significant day-to-day price fluctuations — as occurred around Nvidia earnings releases, AI-sector news events, and broader market dislocations — the compounding of daily returns over extended holding periods produces a cumulative result that can be lower than a static 2x leverage ratio would imply. The more volatile the path, the greater this drag can be. Nvidia's high-beta profile amplified the effect throughout the period, resulting in a meaningful gap between the leveraged daily return objective and the fund's realized cumulative return.

Fund Objective

The T-REX 2x Long Tesla Daily Target ETF (“TSLT” or the “Fund”) seeks daily investment results, before fees and expenses, of 200% of the daily performance of Tesla common stock ("TSLA").

Fund Performance

For the fiscal year ended June 30, 2026, TSLT returned 23.48%, compared to a 32.41% return for TSLA and 22.32% for the S&P 500® Index.

Performance Drivers

Tesla delivered a meaningful positive return over the fiscal year as investors responded constructively to the company's progress across multiple growth vectors — including advances in fully autonomous driving, commercial development of the Optimus robotics platform, accelerating energy storage deployments, and improving profitability metrics. However, the stock's characteristically wide intra-period price swings — at times driven by delivery data, regulatory developments, management commentary, and shifting competitive dynamics — reduced the benefit of the Fund's daily leveraged exposure on a cumulative basis. As with all daily reset leveraged funds, periods of sharp two-way volatility can erode the compounding advantage that would otherwise accompany a sustained directional trend, which resulted in a cumulative return that fell meaningfully short of twice Tesla's annual gain.
